Dynamic check digit utilization via electronic tag

ABSTRACT

An exemplary system and method allowing for dynamic verification that cargo is being placed onto the correct carrier for transit is disclosed. The system may employ voice recognition to capture dynamically generated check digits from a display to verify the digits against a cargo record, thereby confirming that the cargo is being placed on the correct carrier. A voice enabled workflow allows a worker loading cargo to speak the last “n” digits on the identifying label of a piece of cargo to first uniquely identify the piece of cargo being handled. Once the cargo is identified, the system can direct the worker to the proper carrier into which the cargo should be placed. The worker then reads a unique “check digit” code generated on an electronic tag located in the carrier. The code is then verified by the system to confirm the carrier onto which the cargo was placed.

CROSS-REFERENCE TO RELATED APPLICATION

The present application claims the benefit of U.S. Provisional Patent Application No. 62/097,097 for DYNAMIC CHECK DIGIT UTILIZATION VIA ELECTRONIC TAG filed Dec. 28, 2014. The foregoing patent application is hereby incorporated by reference in its entirety.

FIELD

Embodiments of the present invention generally relate to the field of logistics management and, more specifically, to a system that allows voice confirmation of a dynamic check digit code to verify that a parcel is being sorted, routed, and delivered properly.

BACKGROUND

When sorted and prepared for delivery, packages (i.e., cargo, parcels, containers, crates, etc.) are typically classified based upon the specific delivery location for the package, assigned to a delivery route, and loaded onto a delivery vehicle either by a sorter or by a delivery driver. Carriers that deliver packages, or that load and sort cargo, need a real-time solution to confirm that the cargo or parcels being sorted are routed correctly. This process requires verification that the cargo is being placed in a given transit carrier delivery truck in order to confirm that the cargo is on the correct carrier (e.g., that the cargo is following the scheduled route, that the associated route stops that will carry the cargo to the correct destination, etc.).

Although a worker can scan a bar code inside the truck for each package that is placed therein, this solution requires that the worker stop and free up a hand to operate the scanner in order to scan both the cargo and the barcode in the transit vehicle. This negatively impacts the ergonomics and labor costs associated with requiring a hands-busy worker to alter their progress and work flow in order to complete the scanning process for each piece of cargo. The requirement that a worker handle a scanner and serially scan the cargo in order for the carrier to confirm routing can be cost prohibitive.

Therefore, a need exists for improved cargo tracking processes, including but not limited to a hands-free system for confirming the routing information for a package.

SUMMARY

The present disclosure relates to a method and system allowing for dynamic verification that cargo is being placed onto the correct carrier (e.g., the correct delivery truck or other delivery vehicle) for transit along the proper routing. The system employs voice recognition to capture dynamically generated check digits from an electronic tag—an “eTag” display—to verify the check digits against a cargo record database thereby confirming that the cargo is being placed on the correct carrier.

The present disclosure provides for the use of a voice enabled workflow wherein a traditional barcode scanner may be replaced with a voice recognition system. A worker loading cargo speaks the last “n” digits on the identifying label of a piece of cargo to first uniquely identify the piece of cargo being handled. This information is transmitted to a server. Once the cargo is identified and located in the shipping manifest by the server, the system directs the worker to the proper carrier into which the cargo should be placed.

In traditional methods, when the worker placed the cargo into the carrier the worker utilized a barcode scanner to scan both the cargo and a tag in the carrier. This information was utilized by the system to confirm correct placement. In the present disclosure, instead of scanning the cargo and the carrier, the worker reads a unique “check digit” code generated on an eTag display located in the carrier. The unique code is then verified by the system to confirm the carrier onto which the cargo was placed.

The present disclosure may include use of ID digits on the cargo and a voice recognition system to capture the ID digits, as well as the concept of dynamically generated “check digit” codes on the eTags within the carrier. This process makes the unique value completely dynamic for each and every worker interaction as opposed to either completely static with paper labels, or slightly variable by using a predetermined list of permutations based on a label with a matrix of values.

In one embodiment, the system utilizes a random number generator so that each interaction uses a different number over a programmable period of time. This solution prevents a common problem known as “check digit memorization” where voice workers visit the same locations often enough that they know and can speak the check digit value before reaching the correct location.

Further, the eTags may be mounted inside each carrier in a way that they can only be viewed by the worker when they are extremely close to the cargo bay of the carrier so that there is no chance of reading the correct check digit value while also putting the parcel on the wrong carrier.

In an alternate implementation, a predetermined synchronization between the application and the eTag can be implemented to reduce the cost and the power requirements of the electronic tag.

The foregoing illustrative summary, as well as other exemplary objectives and/or advantages of the invention, and the manner in which the same are accomplished, are further explained within the following detailed description and its accompanying drawings.

DETAILED DESCRIPTION

Referring now to the drawings (FIGS. 1-3), a method and system that allows dynamic verification that cargo is being placed onto the correct carrier for transit along the proper routing is shown and illustrated. The system can employ voice recognition to capture dynamically generated check digits from a display to verify the generated digits against a cargo record database, thereby confirming that the cargo is being placed on the correct carrier.

The operation and interaction of the voice recognition system, and the wireless communication between the application server and the headsets, is known in the art and will not be discussed in detail herein. Additionally, the overall package workflow and database systems that enable high volume package routing are also known, and will not be discussed in detail.

As set forth above and shown schematically at FIG. 1, the present disclosure provides for the use of a voice enabled workflow wherein a traditional barcode scanner (or other data entry device) may be replaced with a voice recognition system 10 that may be contained on a server. In tradition systems, a worker had to handle a scanner to determine where cargo was being routed and to verify placement of the cargo at the correct carrier location. When the worker placed the cargo into the carrier, the worker would scan both the cargo and a tag in the carrier again in order to update the system. This required that the worker frequently interrupt their workflow in order to pick up and utilize the scanner.

In the exemplary system, a worker 12 loading cargo 14 speaks the last “n” digits 16 (e.g., 123) on the identifying label 18 of a piece of cargo 14. A headset 20 or other speech enabled device transmits the spoken last “n” digits 16 to the voice recognition system 10 to uniquely identify the piece of cargo 14 that the worker is handling. Once the cargo 14 is identified, the system 10 locates and verifies the cargo 14 against a cargo record database and directs the worker 12 to the proper carrier 22 into which the cargo 14 should be placed (e.g., “Place the Package in Carrier ABC”).

In the exemplary system, instead of scanning the cargo 14 and a tag in the carrier 22 as was done in traditional systems, the worker 20 reads a unique “check digit” code 24 generated on an electronic tag “eTag” 26 located in the carrier 22. The eTag 26 may be a simple wireless device with a display (e.g., LCD, e-ink, etc.). The code 24 is then transmitted to the system 10 and verified by the system to confirm the carrier 22 onto which the cargo 14 was placed. FIG. 3 is a simplified flow chart of the basic system operation as generally described herein.

As set forth herein, the exemplary system makes novel use of the voice recognition system to capture the cargo ID digits as well as the concept of dynamically generated “check digit” codes from the eTags within the carrier, making the unique combination of values completely dynamic for each and every worker interaction as opposed to either completely static with paper labels, or slightly variable by using a predetermined list of permutations based on a label with a matrix of values.

In one embodiment, the system may utilize a random number generator so that each interaction uses a different number over a programmable period of time. This solution prevents a common problem known as “check digit memorization” where voice workers visit the same locations often enough that they know and can speak the check digit value before reaching the correct location.

Further, the eTags may be mounted inside each carrier in a way that the eTags can only be viewed by the worker when the worker is extremely close to the cargo bay of the carrier so that there is no chance of reading the correct check digit value while also putting the parcel on the wrong carrier.

In another implementation, a predetermined synchronization between the application and the electronic tag can be implemented to reduce the cost and the power requirements of the electronic tag. In this case, the system server 10 may periodically generate the “check digit” and provide it to the eTag or, vice versa, the eTag may periodically generate the “check digit” on a predetermined schedule and synchronize it with the server 10. Wireless interaction between the headset 20, voice recognition system/server 10, and the eTag 26 is generally shown at FIG. 2.

While the exemplary system is illustrated in the context of a wireless headset, the system anticipates implementation via wireless headsets, wired headsets, worker mounted integrated voice recognition and hands free scanner devices, vehicle mounted voice recognition computing devices, and mobile worker workstations (among other configurations). These various devices may be integrated through flexible connectivity of devices and servers that facilitates the transfer of information beyond the traditional capabilities of voice software. This connectivity provides the launching point for implementing voice-enabled operations to achieve the highest levels of productivity, extendible architecture and the seamless voice-enablement of tasks and workflow execution.

While there is shown and described herein certain specific structures embodying a system that employs voice recognition to capture dynamically generated check digits from a display to verify them against a cargo record thereby confirming that the cargo is being placed on the correct carrier, it will be manifest to those skilled in the art that various modifications and rearrangements of the parts may be made without departing from the spirit and scope of the underlying inventive concept and that the same is not limited to the particular forms herein shown and described except insofar as indicated by the scope of the appended claims.
